In in vitro study on green monkey kidney (GMK) cell culture, the cytotoxicity of Ukrain, methotrexate (MTX), and their combination was investigated. The effect of these drugs and their combination on viability (MTT test) and apoptosis of the cells was assessed. The IC₁₀ and IC₅₀ values for Ukrain and MTX were also indicated. After 24 h of incubation of GMK cells with Ukrain, IC₁₀ amounted to 84.6...
